Good visuals, and an immediately accessible scene selector and CG gallery for those that don't want to experiment to unlock content.
I found the main thing that lets this game down are the sound effects. Sound effects seem to be almost absent from the game, and in the few cases where sounds play, I find they distract from the experience. You can just mute the game and won't be missing anything, so I'd say this is a non-issue unless you are expecting a fully voiced experience.
All in all a good game if you're into SM and slave stuff.
